1.Rubber: A little amount of Nano silica is added into common rubber, the rubber Strength, abrasive resistance, Strength of extension, aging resistance and other properties reach or exceed top grade rubber products, besides, the color doesn’t change for a long time. When it is used to produce colored tire, the breaking resistance on the side of tire is greatly improved.

Some Nano silica could be added into SSBR and ethylene chloride to produce colored rubber products, such as colored water proof roll, yard material and so on. The toughness, strength, elongation, breaking resistance, UV aging and thermal ageing and other properties can extend those of EPDM.
